What Are Digital Keys?

Digital keys are a virtual representation of a vehicle’s key fob, stored on a smartphone or other smart device. They use encrypted communication protocols to authenticate the user’s identity and grant access to the vehicle’s functions.

How Do Digital Keys Work?

Digital keys typically work through NFC or UWB technology. NFC requires the user to hold their smartphone near the vehicle’s door handle to unlock it, while UWB allows for passive entry, automatically unlocking the vehicle as the user approaches. Once inside, the smartphone can be used to start the engine.

Benefits of Digital Keys

• Convenience: No need to carry a physical key fob.
• Sharing: Digital keys can be easily shared with family and friends.
• Customization: Some digital key systems allow for customizable settings, such as speed limits and audio volume restrictions for shared users.

Step 2: Check for Diagnostic Trouble Codes (DTCs)

Use an advanced scan tool to check for any DTCs related to the digital key system. These codes can provide valuable clues about the nature and location of the problem.

Step 3: Inspect the Digital Key Components

Visually inspect the digital key components, including the smartphone, vehicle’s door handles, and any related modules. Look for signs of damage, corrosion, or loose connections.

Step 4: Test the Digital Key System

Test the functionality of the digital key system by attempting to lock, unlock, and start the vehicle. Observe any abnormal behavior or error messages.

Step 5: Analyze Live Data

Use the scan tool to access live data from the digital key system. This data can provide insights into the system’s operation and help identify any abnormal parameters.

Step 6: Perform Software Updates

Check for any available software updates for the digital key system. Updating the software can resolve known bugs and improve the system’s performance.

Step 7: Consult Technical Service Bulletins (TSBs)

Consult TSBs from the vehicle manufacturer for any known issues related to the digital key system. TSBs often provide detailed diagnostic and repair procedures.

Step 8: Seek Expert Assistance

If you are unable to diagnose the problem, seek assistance from an experienced technician or the vehicle manufacturer’s technical support team.
